The Marekerk church was designed by the city architect Arent van ’s-Gravesande in 1639-1649, who also designed the Bibliotheca Thysiana on Rapenburg 25. It was opened in 1649. The main entrance was designed by Jacob van Campen in 1659. The organ was built by Pieter de Swart around 1560 for the choir of the Pieterskerk and it was moved to the Marekerk in 1733 and enlarged by Rudolph Garrels. It was restored in 1966 by Flentrop Orgelbouw.

The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
